Uhhuh. NMI received for unknown reason 2d on CPU 0.
Dazed and confused, but trying to continue.
Do you have a strange power saving mode enabled ?

has anybody received this message through the install process ? and after boot it continually shows up, filling up the /var/log/messages and growing it to massive amount

ACPI is OFF in bios
APIC is OFF in bios
power management is OFF in bios

i tried to boot with: acpi=off noapic

but i get the same results

I have:
Intel Pentium 4 3.2GHz LGA775 processor
MSI 945P MoBo
3GB TwinMos RAM
2x 300GB SATA drives
